GFpECSetPoint, GFpECSetPointREgular¶
Sets up the coordinates of a point on an elliptic curve.
Syntax¶
IppStatus ippsGFpECSetPoint(const IppsGFpElement* pX, const IppsGFpElement* pY, IppsGFpECPoint* pPoint, IppsGFpECState* pEC);
IppStatus ippsGFpECSetPointRegular(const IppsBigNumState* pX, const IppsBigNumState* pY, IppsGFpECPoint* pPoint, IppsGFpECState* pEC);
Include Files¶
ippcp.h
Parameters¶
pX, pY |
Pointers to the |
pPoint |
Pointer to the IppsGFpECPoint context. |
pEC |
Pointer to the context of the elliptic curve. |
Description¶
This function sets up the coordinates of a point on the elliptic curve over the finite field.
Return Values¶
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified pointers is NULL. |
ippStsContextMatchErr |
Indicates an error condition if any of the specified contexts does not match the operation. |
ippStsOutOfRangeErr |
Indicates an error if the point coordinates (pX, pY) do not belong to the finite field over which the elliptic curve is initialized. |
